Harry Edward Nilsson III (June 15, 1941 – January 15, 1994), usually credited as Nilsson, was an American singer-songwriter who achieved the peak of his commercial success in the early 1970s. He is known for the hit singles "Everybody's Talkin'" (1969), "Without You" (1971), and "Coconut" (1972). Nilsson also wrote the song "One" made famous by the rock band Three Dog Night. He was one of the few major pop-rock recording artists of his era to achieve significant commercial success without ever performing major public concerts or undertaking regular tours.

He received Grammy Awards for two of his recordings; Best Contemporary Vocal Performance, Male in 1970 for "Everybody's Talkin'", a prominent song in the Academy Award-winning movie Midnight Cowboy, and Best Pop Vocal Performance, Male in 1973 for "Without You."
